Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a lock box. Background Art

[0002] Lifting sliding doors and windows are a common type of doors and windows, which are characterized by being able to be lifted upward when opened, not occupying indoor or outdoor space, and increasing convenience. The driving mechanism inside the existing transmission lock box of the lifting sliding door usually adopts a crank pull rod method, which requires a large space in the horizontal direction, that is, the width direction of the lock box, which leads to an increase in the overall volume of the transmission lock box. Therefore, the utility model proposes a lock box with a smaller width. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a lock box with a small volume and a small width.

[0004] A lock box according to the first aspect of the utility model comprises a box body, a transmission mechanism and a lock head block, wherein the box body is provided with a handle lock hole, a lock core hole and a column arranged inside the box body, and the column is arranged on one side of the lock core hole; the transmission mechanism comprises a hinged cam and a transmission plate, and the other end of the transmission plate is hook-shaped and extends out of the box body; an installation cavity is provided in the middle of the lock head block, and the lock head block is arranged inside the box body and is movably connected to the column through the installation cavity.

[0005] According to the lock box of the embodiment of the utility model, at least the following technical effects are achieved: the handle lock hole is used to install the handle, the hook-shaped end of the transmission plate can be connected to the movable part of the transmission device of the lifting and sliding door, and the handle can drive the cam to rotate after rotating, and then drive the transmission plate to change position, so that it is possible to use the transmission plate to drive the transmission device of the lifting and sliding door to produce lifting and lowering, thereby driving the pulley assembly connected to the transmission device and installed at the bottom of the door and window leaf to lift and lower; on the other hand, the lock core hole is used to install the lock core, and the lock core has a rotating protrusion, and the rotation of the key can drive the rotation of the rotating protrusion on the lock core, and then the rotating protrusion can change the position of the lock head block, so that the lock head block can be rotated around the column to achieve the purpose of locking the door. In the utility model, the handle controls the lifting and lowering of the door and window, and the lock core controls the locking or opening of the door and window. Both adopt a cam-like form, and use rotation to perform the telescopic displacement of the object, etc., with division of labor and cooperation, and a compact structure, so the purpose of miniaturization design can be achieved.

[0006] According to some embodiments of the present invention, the lower portion of the lock block is an arc-shaped portion, one side of the lock block is a hook portion, the installation cavity is provided with an elastic member, and both ends of the elastic member are respectively abutted against the column and the inner wall of the installation cavity.

[0007] In the above scheme, when the key is rotated to drive the rotating protrusion on the lock core to rotate, the rotating protrusion can move the arc-shaped part of the lock block during the rotation process and then drive the entire lock block to change its position, so that the lock block rotates around the column, thereby extending the curved hook part on one side of the lock block to the outside of the lock box, and then hooking the locking mechanism outside the lock box; in addition, due to the action of the elastic part, when the key is rotated, the lock block can be reset, and the curved hook part will retract into the inside of the lock box, thereby achieving the purpose of opening the door.

[0008] According to some embodiments of the utility model, an extension protrusion is arranged on the upper portion of the lock block, and a limit block matched with the extension protrusion is arranged inside the box body.

[0009] In the above scheme, when the rotating protrusion rotates and then drives the lock block to move around the column, the extension protrusion will abut against the limit block, and after abutment, the rotating protrusion will continue to drive the lock block to move. At this time, the lock block will no longer rotate with the column as the fulcrum but will continue to rotate with the position where the extension protrusion and the limit block abut as the movement fulcrum. In this way, the lock block can fully extend out of the lock box.

[0010] According to some embodiments of the utility model, the installation cavity is provided with a first curved waistline groove, a second curved waistline groove and a columnar cavity, one end of the first curved waistline groove and one end of the second curved waistline groove have a smooth transition, the other end of the first curved waistline groove and the other end of the second curved waistline groove are both connected to the columnar cavity, and the curvature of the first curved waistline groove is greater than the curvature of the second curved waistline groove.

[0011] In the above scheme, the elastic member is arranged in the cylindrical cavity, so that the elastic member is not easy to fall off. The lock core can rotate the rotating protrusion by turning the key, and the rotating protrusion will abut against the inner side wall of the arc-shaped portion when it rotates. Before the rotating protrusion rotates at the beginning, it contacts the lowest position of the arc-shaped portion. At this time, the lock head block is at the lowest height position under the action of the elastic member. At this time, one side of the column abuts against the upper part of the second curved waistline groove. Since the curvature of the first curved waistline groove is greater than the curvature of the second curved waistline groove, the lock head block will not change position without external force. When the rotating protrusion rotates, the rotating protrusion slowly moves from the bottom of the arc-shaped portion to the top of the arc-shaped portion until it contacts the arc-shaped portion. The lock block is at the highest position of the inner wall of the part, during which the lock block is obliquely lifted up by the rotating protrusion and changes from rotating around the column to rotating around the limit block to reach the highest height position. At this time, the lock block at the highest height position is affected by the elastic member and the column at the same time, and an angle deflection occurs, thereby realizing that the curved hook portion on the lock block is bent and extended to the outside of the lock box plane, thereby achieving the door locking effect. At this time, the lock block abuts against the column in the middle of the second curved waistline groove; on the other hand, when the key is turned back, the external force disappears, and the lock block can be finally pushed to the lowest height position through the rebound of the elastic member, thereby realizing the resetting of the curved hook portion and hiding it inside the box body to achieve the door opening effect.

[0012] According to some embodiments of the present utility model, the drive plate is installed on one side of the cam, a relief groove adapted to the drive plate is provided on the side of the cam, and a stop block is provided at the end of the relief groove on the upper part of the cam.

[0013] In the above solution, the drive plate is displaced on one side of the cam, and the rotation of the cam can drive the drive plate to move up and down.

[0014] According to some embodiments of the present utility model, the elastic member is a spring.

[0015] According to some embodiments of the present utility model, the inner diameter of the installation cavity is greater than the outer diameter of the column body.

[0016] In the above solution, when the lock head block rotates around the column body, the column body does not move, the elastic member is stuck in the cylindrical cavity and rotates with the lock head block. The inner diameter of the installation cavity is larger than the outer diameter of the column body, so that the rotation of the lock head block can be an irregular deflection around the column body rather than a rotation centered on the column body.

[0017] According to some embodiments of the present utility model, the box body includes a front panel and a rear panel, a sliding plate is slidably arranged between the front panel and the rear panel, a hook hole adapted to one end of the hook-shaped drive plate is provided on the upper part of the sliding plate, and a strip-shaped through groove for the bent hook part to pass through and move is provided on the lower part of the sliding plate.

[0018] In the above solution, the hook-shaped end of the drive plate can be connected to the hook hole to realize the connection between the drive plate and the sliding plate. In this way, when the drive plate moves up and down, it can drive the sliding plate to move. The sliding plate is one of the conventional basic components of the box body for lifting the sliding door, and the sliding plate is used to connect the drive structure of the lifting sliding door. On the other hand, during the up and down sliding process of the sliding plate, the bent hook part passes through the strip-shaped through groove and will not interfere with the sliding plate.

[0028] As Figures 1 to 4 shown, the lock box according to the first aspect embodiment of the present utility model includes a box body 1, a transmission mechanism and a lock head block 7. The box body 1 is provided with a handle lock hole 2, a lock core hole 3 and a cylinder 11 arranged inside the box body 1. The cylinder 11 is arranged on one side of the lock core hole 3; the transmission mechanism includes a cam 4 and a transmission plate 5 which are hinged, and the other end of the transmission plate 5 is in a hook shape and extends out of the box body; an installation cavity 10 is arranged in the middle of the lock head block 7, and the lock head block 7 is arranged inside the box body 1 and is movably connected to the cylinder 11 through the installation cavity 10.

[0029] Specifically, the handle lock hole 2 is used to install the handle, and the hook-shaped end of the transmission plate 5 can be connected to the movable part of the transmission device of the lifting and sliding door. When the handle is rotated, the cam can be driven to rotate, and then the transmission plate 5 can be driven to change its position. In this way, it is possible to use the transmission plate 5 to drive the transmission device of the lifting and sliding door to produce lifting and lowering, thereby driving the pulley assembly connected to the transmission device and installed at the bottom of the door and window leaf to lift and lower, thereby achieving the purpose of opening and locking the door; on the other hand, the lock core hole 3 is used to install the lock core, and the lock core has a rotating protrusion. The rotation of the key can drive the rotation of the rotating protrusion on the lock core, and then the rotating protrusion can drive the lock head block 7 to change its position. In this way, the lock head block 7 can be rotated around the column 11 to achieve the purpose of locking the door.

[0030] In some specific embodiments of the present invention, the lower part of the lock block 7 is an arc-shaped part 8, one side of the lock block 7 is a hook part 9, and the installation cavity 10 is provided with an elastic member 12, and the two ends of the elastic member 12 are respectively abutted against the column 11 and the inner wall of the installation cavity 10.

[0031] Specifically, when the key rotates and drives the rotating protrusion on the lock core to rotate, the rotating protrusion can move the arc portion 8 of the lock block 7 during the rotation process and then drive the entire lock block 7 to change position, so that the lock block 7 rotates around the column 11, thereby extending the curved hook portion 9 on one side of the lock block 7 to the outside of the lock box, and then hooking the locking mechanism outside the lock box. In addition, due to the action of the elastic member 12, when the key is turned back, the lock block 7 can be reset, and the curved hook portion 9 is retracted into the interior of the lock box 1, thereby achieving the purpose of opening the door.

[0032] In some specific embodiments of the present invention, an extension protrusion 15 is provided on the upper portion of the lock block 7 , and a limit block 16 matched with the extension protrusion 15 is provided inside the box body 1 .

[0033] Specifically, when the rotating protrusion rotates and then drives the lock block 7 to move around the column 11, the extension protrusion 15 will abut against the limit block 16. After abutment, the rotating protrusion continues to drive the lock block 7 to move. At this time, the lock block 7 will no longer rotate with the column 11 as a fulcrum, but will continue to rotate with the position where the extension protrusion 15 and the limit block 16 abut as the movement fulcrum. In this way, the lock block 7 can fully extend out of the lock box 1.

[0034] like Figure 3As shown, in some specific embodiments of the present utility model, the installation cavity 10 is provided with a first curved waistline groove 101, a second curved waistline groove 102, and a cylindrical cavity 103. One end of the first curved waistline groove 101 and one end of the second curved waistline groove 102 are smoothly transitioned. The other end of the first curved waistline groove 101 and the other end of the second curved waistline groove 102 are both connected to the cylindrical cavity 18. The radian of the first curved waistline groove 101 is greater than that of the second curved waistline groove 102.

[0035] Specifically, the elastic member 12 is disposed within the cylindrical cavity 103, such that the elastic member 12 is not easily detached. The rotation of the key by the lock core can cause the rotation of the rotating convex block. When the rotating convex block rotates, it will abut against the inner side wall of the arc portion 8. Before the rotating convex block starts to rotate, its lowest position in contact with the arc portion 8 is at this time. The lock head block 7 is at the lowest height position under the action of the elastic member 12. At this time, one side of the column 11 abuts against the upper part of the second curved waistline groove 102. Since the radian of the first curved waistline groove 101 is greater than that of the second curved waistline groove 102, without external force, the position of the lock head block 7 will not change; when the rotating convex block rotates, the rotating convex block moves from the bottom of the arc portion 8 towards the top of the arc portion 8 until it touches the highest position of the inner wall of the arc portion 8. During this period, the lock head block 7 is obliquely pushed up by the rotating convex block and changes from rotating around the column 11 to rotating around the limiting block 16 to reach the highest height position. At this time, the lock head block 7 at the highest height position is affected by both the elastic member 12 and the column 11, and an angular deflection occurs, and then the hook portion 9 on the lock head block 7 bends and extends outside the plane of the lock box 1, achieving the effect of locking the door. At this time, the lock head block 7 and the column 11 abut against the middle part of the second curved waistline groove 102; on the other hand, when the key is rotated back and the external force disappears, through the rebound of the elastic member 12, the lock head block 7 can be finally pushed to the lowest height position, and then the hook portion 9 is reset and hidden inside the box body 1 to achieve the effect of opening the door.

[0036] As Figure 4 Shown, in some specific embodiments of the present utility model, the transmission plate 5 is installed on one side of the cam 4. A relief groove 13 adapted to the transmission plate 5 is provided on the side of the cam 4. A stop block 14 is provided at the end of the relief groove 13 on the upper part of the cam 4.

[0037] Specifically, the transmission plate 5 is displaced on one side of the cam 4. The rotation of the cam 4 can drive the transmission plate 5 to perform vertical displacement.

[0038] In some specific embodiments of the present utility model, the elastic member 12 is a spring.

[0039] In some specific embodiments of the present utility model, the inner diameter of the installation cavity 10 is greater than the outer diameter of the column 11.

[0040] Specifically, when the lock head block 7 rotates around the cylinder 11, the cylinder 11 remains stationary. The elastic member 12 is stuck in the cylindrical cavity 103 and rotates with the lock head block 7. The inner diameter of the installation cavity 10 is larger than the outer diameter of the cylinder 11, so that the rotation of the lock head block 7 can be an irregular deflection around the cylinder 11 rather than a rotation centered on the cylinder 11.

[0041] In some specific embodiments of the present utility model, the box body 1 includes a front panel 17 and a rear panel 18. A slide plate is slidably arranged between the front panel 17 and the rear panel 18. An engaging hole adapted to one end of the hook-shaped transmission plate 5 is arranged at the upper part of the slide plate, and a strip-shaped through groove for the bent hook portion 9 to pass through and move is arranged at the lower part of the slide plate.

[0042] Specifically, the hook-shaped end of the transmission plate 5 can be connected to the engaging hole to realize the connection between the transmission plate 5 and the slide plate. In this way, when the transmission plate 5 moves up and down, it can drive the slide plate to move. The slide plate is one of the conventional basic components of the box body for lifting and sliding doors, and the slide plate is used to connect the transmission structure of the lifting and sliding doors. On the other hand, during the up and down sliding process of the slide plate, the bent hook portion 9 passes through the strip-shaped through groove and will not interfere with the slide plate.
